s'rIcKING PINS IN PAPER.

Specification of'Letters Patent No. 15,877, dated October 14, 1856.

To all wiz-0m t may concern:

Be it known that I, WALKER B. BAR'rRAM, of lVaterbury, in the county ofNew Haven and State of Connecticut, have invented a new and ImprovedMachine for Sticking Pins in Paper; and I do hereby declare that thefollowing is `a full, clear, and exact description of the same,reference being had to the annexed drawings, forming part of thisspecification, in which Figures 1 and 2, are vertical sections at rightangles to each other taken'` through the principal parts of the machine.Fig` 3, is a plan of the same. Fig. 4, is a plan of part of the machineindetail. Figs. `5, 6 and tail. p

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in certain new devices and in certain'newarrangements `and combinations of old devices, the whole constituting amachine of novel character for crimping the paper and sticking the pinstherein. 1

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A, is the framing of the machine.

C, is the shaft from which all the working parts of the machine derivetheir necessary movements. This shaft works in bearings a, a, on the topof and near one end of the framing. i

B, is a roller whichcarries the paper, c, into which, after it has beencrimped, the pins are to be stuck, said paper being in a V continuousroll of an indefinite length.

This roller has its journals fitted to bearings Z1, arranged on the-topof the framing at the opposite end to the shaft C.

D, and E, are two rollers hung in bearings in the lower part of theframing, carrying an endless band cl, of india rubber of a width notless `than the width of the paper.

F, is a roller which is arranged in bearings in the lower `part of theframing in such a position that the band (Z eXerts a pressure against aconsiderable portion of its periphery for the purpose of taking hold ofthe paper c, to draw it from the roller B, as fast as it is required,the drawing of the paper being effected by an intermittent motion of theroller F, produced by a ratchet wheel G, at'one end of the said roller,which is operated upon at proper intervals by a 7. are side views ofsome of the cams in de-` dog e, suspended from one end of an elbow leverH, actuated by a simple wiper J, on `the shaft C.

I, 71, see Fig. 1, are the crimpers, of which two pair will `always beused, though I have only shown one pair for the sake of simplifying andpreventing obscurity in the drawing. These crimpers are of a well-knowncharacter. They are constructed and arranged to advance toward `andrecedel from each other by sliding in grooves in a guide piece I', inthe lower part of the guide frame K, in which the pin driver L, works,as shown in Fig. 2. The movement of the female crimper I, is produced byits connection with the arm m, of a rock shaft M, arranged below inbearings in the frame A, and the movement of the male crimper c', by itsconnection with the arm n, of a rock shaft N, arranged relatively toitsubstantially as M is to the female crimper, I. The rockshaft M isfurnished with another arm m2, which is operated upon to work the femalecrimper I, by a cam M', on the shaft C, and the rock shaft N, isfurnished with a short arm n2, whichisconnected by a rod n', with alever N2, which is operated upon to actuate the male crimper z', by acam N', on the shaft C. `The cams M', N', are simply what are generallyknown as wipers, as they are required to make the crimpers advancequickly to meet each other and to allow them. to retreat quickly. Theretreating movement of the crimpers is effected by springs m3, as,applied to the arms m2, a2, of their respective rockshafts.

O, 0*, are the jaws of a pair of forceps which seize the fold of thecrease produced by the crimpers after the latter have retreated, forthepurpose of holding the `said crease closed and in a rigid conditionwhile the pins are inserted through it. The arms j, j, of these forcepswork on separate stationary pivots la, c, and are operated upon to closethe jaws of the forceps by means of two wipers or cams O', 0", on theshaft C. The forceps are opened again after they have finished theirduty, by a spring Z, connecting the two arms j, j, above the pivots 71:,t. i Two pairs of forceps will be required for two pairs of crimpers,viz., one for each pair of crimpers, but both will op erate insubstantially the same manner.

` P, P*, are a pair of aws which constitute a holder to hold the pins t,t, upright in readiness for driving through the crease formed in thepaper and until after the commencement of the driving operation. Thesejaws are attached to two levers p, 29,* which work on separate fixedpivots g, g* and are 5 operated upon to close the jaws by cams P, P*, ofwhich separate views are'shown in Figs. 6 and 7. The jaws are liberatedat the proper time by the connection of the two levers p, 2),* by `aspring 7, see Fig. 1. The 10 jaw P, contains strips of leather s, s,which project slightly beyond its face so as to constitute the surfaceswhich hold the pins t, t, against the face of the other jaw, by whichmeans the pins are held with firmness enough to prevent them getting outof a proper position, but are allowed to move longitudinally under theaction of the driver I.

Q, is a movable jaw occupying a position below the jaw P, and intendedto operate in connection with the upper jaw of the forceps O, 0*, as asecond holder of a similar character to P, Pt, the jaw O, of the forcepsbeing furnished with a strip of leather in the face next the jaw Q, likethe face of the jaw Pt, of the upper holder. The jaw Q, is slotted forthe male crimper z', to pass through it. It is attached to the arm u, ofa rock shaft R, which is arranged in bearings between the shafts N, M.This rock shaft is furnished with a shorter arm u, which is connected bya rod u2, with a lever R2, that is operated upon to bring the jaw Q,toward the forceps O, 0"", by a cam R', on the shaft C. The jaw Q, isthrown back again when it is time to release the pin by means of aspring that is applied to the arm u', but not visible in the drawing.

S, is the pin feeder, consisting of a sta- 10 tionary slotted inclinedbar in the slot o, of which the pins hang suspended vertically by theirheads, which are broader than the slot o. The inclination of the barterminates at a short distance from its lower extremity where, for ashort distance, it gradually assumes a horizontal direction to meet ahorizontal slotted plate T, which is fitted to slide in a directiontransverse to the movement of the paper, in guides w, fw. The lowerextremity of the feeder must not extend laterally beyond the position tobe occupied by the last pin of a row. The slot o, which forms acontinuation of the slot o, into the plate T, is of a length not lessthan that of a row of pins. The slot o, receives from the feeder' asuiicient number of pins to form a row and keeps them suspended invertical positions till the holders take them, after which the plate T,is drawn outward from the machine to make room for the hammer to drivethe pins through the holders into the creases of the paper. The slidingmotion of the plate back -and forth is produced by the action of a camT, on a horizontally-moving lever T2, which works at one end of a fixedfulcrum and at the other end takes hold of the plate by a slot and pinconnection.

y, y, y2, yg, etc., are a series of angular bars corresponding in numberto the nurnber of pins to be inserted in one row, constituting what Icall the separator, the duty of which is to take a proper number of pinsfrom the bottom of the feeder, separate them and force them in the sloto', of the plate T, 75 over the holders at the proper distance apart forinsertion in the paper. These bars y, y, etc., are fitted to slide sideby side transversely of the machine in a guide box, U, which 1s arrangedto swing backward so and forward in the machine on a pivot c,

and receives such swinging movement in a forward direction or toward thepins from a short wiper 10, on the shaft C, acting on the upper end of alever 11, which is connected at its lower end by a rod 12, with a rigidupright 13, attached to the guide box, but receives its backwardmovement from a spring 23, applied to the upright 13. The forwardswinging movement of the box U, takes place at a time when the points ofthe separating bars y, y, etc., are as close as possible together andall opposite to the same lower part of the feeder. The points of thebars in that condition are at a dis- 95 tance apart corresponding withthe diameter of the heads of the pins, and as the bars swing forwardwith the box, the shanks of the pins being at a short distance apartowing to the greater size of the heads, the said points pass between thepins. The bars y, y', etc., then slide in the box U, one after the otherin quick succession, the bar y, which takes the first pin, moving iirstand thus moving the pins away from each other as fast as requiredaccording to the spaces required between them on the paper. The slidingmovement of the separating bars y, y, etc., in the box U, is produced bya cam V, on the shaft C, acting on a horizontally-moving lever V, oneend of which works on the fulcrum pin 14:, and the other connects with apin 15, on the top of a saddle 16, which slides between the guides ofthe plate U, and rests within notches 17, 17 in the upper sides of theseparating bars. These notches 17 are all of different lengths, that inthe bar y, being only just long enough to receive the saddle so that thebar begins to move as soon as the saddle, that in the next bar y, beinga little wider, so that the saddle moves a little way before it operateson the bar, that in the bar y2, being wider still and so on to the lastbar g5. The separating bars are shown in Fig. 4 close together, as theyare before their action, and in Fig. 1 open in the act of separating thepins.

V, is a horizontal lever working on a fulcrum 18, and serving as a stopto prevent 130 the feeder.

the pins issuing from the feeder till the proper time. This lever isoperated in such manner by a pin connection at 19, with the lever V,that one end is thrown across the underside of the notch o, of thefeeder after the sliding movement of the separating bars in the plate U,and thus stop the pins in This lever is moved out of the way when thepins are to be taken from the feeder by an angle bar if, which stands inadvance of and moves along with the first `pointed separating bar y.

The pin driver L which has been before mentioned, for driving the pinsinto the paper, is attached toa stock K, which slides `in vertical waysin the standard K. Tt has a row of recesses 20, 20, see Fig. 2, countersunk in its face, corresponding in number with the pins to be inserted,each recess being of proper size and occupying a proper position toreceive the head of a pin. These recesses are to hold the upper parts ofthe pins after the points are entered in the crease of the paper andthus serve to hold the pins upright after the jaws of the holder haveopened, which it is desirable they should do as early as possible afterhaving guided the points of the pins to the proper' place in the paper.The pins make their own holes as they enter the paper, no previouspunching being required.` The downward movement ofthe driver to drive inthe pins is produced by a cam L', one end of which works on a fulcrum2l, andthe other is attached by a slet and pin connection 22, with thestock K. The driver is raised again by a spring 24, connecting it withthe top of the standard K. l

The operation of the machine is as follows: The paper from the roll isconducted over the top of the jaw Pt, of the holder, down below the jawsPf, P, and between the ends of the forceps O, O, and bar Q, from whenceit descends to the roller F, passing between the said roller and theband al. The shaft C, has then a rotary motion imparted to it by anysuitable method. The first part of the operation is that of crimping thepaper to form the crease or creases to receive a row of pins. Thecrimpers i, effect `this part of the operation while the holder P, Pf,is open and the paper is free to come from the roll to supply theqnantity taken up in forming the creases. During the operation of thecreasers the boX U, receives its movement toward the pins in the lowerpart of the feeder and its bars y, y after taking a sufiicient number ofpins, slide one by one under the plate U, which is at this time close upto the bottom of the feeder and thus place the pins at proper distancesapart in the slot 'v, of the said plate. The crimpers now move out ofthe way and the holder comes into operation and seizes both the pins andthe paper alongside of them, about the same time as the forceps comeinto operation to seize the crease or creases, and then the box U,swings back to carry the separating bars from between the pins, and theplate T, slides outward from the machine to make room for the descent ofthe driver which comes down and drives the pins through the crease, theholders opening as soon as the heads of the pins have been receivedwithin the recesses in the face of the driver and their points enteredin the first crease, in order to let the driver pass down between them.The driver after its operation is quickly raised by the spring 24, andthe plate T is pushed up again to the feeder, after which the lever Hwith its dog e, comes into operation on the ratchet Gr, and moves thewheel F, ,which takes away the row of stuck pins and draws from the rollB, a supply of paper sufficient to receive the neXt row, after which theabove described operations are repeated with every revolution of theshaft D. The paper having the pins stuck in itis conveyed away betweenthe roller F., and band d, to any suitable receptacle, from which it maybe taken and cut into any lengths desired and folded up ready for themarket. It should be observed that the separating bars, after havingbeen thrown back from between the pins by the swinging movement of thebox U, are caused to slide back,

one at a time, to the position (close together) which they occupied inthe first part of the above described operation, to be in readiness totake another supply of pins` from the pin feeder S. When the bars moveforward to take the pins, the outermost bar gft, knocks away the stoplever V, from in front of the pins. As the last bar i 5, moves fromunder the feeder toward the plate T, the pins in the feeder S, arecaused to follow it by the action of gravitation on those pins in theinclined part of the feeder. As the bar g5, reaches the point where thefirst bar g5, and thus prevents the pin moving moved forward, the stopV, is thrown across the slot e between the front pin and the said bargf, and t-hus prevents the pins moving any farther, and detains thelowest pins in a position ready for the next operation of the spacer andseparator.

This machine possesses several advantages over those in common use for asimilar purpose, among which may be mentioned, first, owing to thepeculiar manner of separating the pins and carrying them toward the devices by which they are placed in the paper it is almost impossible toleave out a single pin from a row, while in the machines in common use,in which the pins are taken one at a time by the separator, so many pinsare missed that much time is lost in supplying their places by hand;second, the work is much more easy and simple for the person in chargeof the machine and a much greater amount of Work is performed in a giventime; third, the pins are held more firmly in the paper owing to thecrease being held closed by forceps during the insertion of the pinsthrough it and afterward slightly opened by the tension produced on thepaper in drawing it through the machine, which causes the paper to biteupon the pins; fourth, the sharp front edges of the crease produced bythe forceps gives the paper a neater appearance.

l/Vhat claim as my invention and desire to secure by Letters Patent, isfl. The separator and spacer composed of a series of bars g/,y,y2,etc.,having a simultaneous movement at right angles or nearly so to theline of pins in the pin feeder and to the line in which the pins areinserted and a movement one after the other in a direction parallel ornearly so to the said line and operating substantially as and for thepurpose herein set forth.

2. The construction of the driver L, with recesses in its face toreceive the heads of the pins and act in conjunction with the paperafter the points of the pins have penetrated it to serve the purpose ofguiding the pins straight and parallel through the paper, thus enablingthe holder to be opened to make room for the driver, substantially asherein described.

3. The stop V, acting in combination with the separator and spacer,substantially as described, to retain the pins behind the separator andspacer after a number suficient for one row has been taken from thefeeder by the separator and spacer, but to be moved away by theseparator and spacer.

et. The bar Q, operating in combination with the forceps O, O,substantially as de-` scribed to form a second holder below theprincipal holder P, Pf, and more perfectly secure the upright andparallel positions of the pins during the commencement of the drivingoperation.
